Tu Fui, Ego Eris

Tu Fui, Ego Eris is a line spoken in Silent Hill 3. It is written and spoken in Latin, and translates into: "As you are, I was; as I am, so you shall also be". The line is spoken by Heather Mason, having read it in the fairy tale scattered in notes throughout the building, to make the Glutton monster disappear. Prior to the words, the Glutton is impassable and cannot be harmed by Heather.

It may be noted that this phrase is also found transcribed on a plaque within the Capuchin crypts of Rome, Italy, in an ossuary that allows visitors to view the skeletons of deceased monks so as to reflect upon their own mortality.

Symbolism

It is possible that the fairy tale was written by Claudia Wolf herself as a young child, or it may have been one of Claudia's storybooks. Heather remembers borrowing it from a friend, which may be Claudia, as Heather has Alessa's memories.

It is possible that the priestess in the fairy tale represents Claudia. The monster itself could represent Harry Mason, as Heather reads the fairy tale not long before she discovers her father has been murdered. Claudia views Harry as a "monster" for stealing her childhood friend, Alessa Gillespie, away from her. This is evident when Claudia mockingly says Harry's name to Douglas Cartland ("That man, Harry Mason, stole her away and kept her hidden from us").

It is possible for the monster to reflect entrapment, in that the monster is barring people from being free. This may symbolize Claudia wishing to defeat the monster (possibly Harry) so that everyone can be free, attaining to her belief of a paradise that Harry is preventing.

The monster, Harry, having been indirectly killed by the priestess, Claudia, to bring happiness to other people.

The act of killing the monster in the fairy tale apparently "had to be done". This strongly relates to Claudia's feelings toward Harry, who she believes must be murdered to birth God, in turn, giving everyone (in the fairy tale, the village) happiness. If the fairy tale was written by Claudia, then it would also correspond to the priestess being a "very, very kind" person; Claudia does not see herself as evil or self-righteous, but believes she is doing good for the world by trying to resurrect the Order'sgod and bringing salvation and Paradise to the people.

The priestess also uses words to indirectly kill the monster; likewise, Claudia uses the Missionary to indirectly kill Harry. Heather has no choice but to get rid of the monster, as it blocks her way out of the Hilltop Center, thus she can be seen reiterating the role of the priestess.

The priestess's resurrection may also be a reference to Valtiel and the fact that he always resurrects Heather if she dies. If this were the case, Alessa/Heather can simply be considered the priestess and the Glutton as the beast.
